The main components are
Coil (electromagnetic)
Housing, metal frame
Magnetic piston
Spring comes back.
“Assembly of core”
Mounting holder
Electrical connectors
The coil generates a magnetic field when DC voltage is applied, which in turn exerts force on the plunger. The actuator can make either push movement, pull movement, or push-pull movement depending on the design.
An experienced frame push-pull solenoid manufacturer designs the actuator based on the requirements of force, stroke, voltage, duty cycle, and installation condition.

Chapter 10: Advice to Avoid Common Mistakes in Choosing a Frame Push-Pull Solenoid Manufacturer
Choosing the right frame push-pull solenoid manufacturer is an essential step for engineers, OEM buyers, and equipment manufacturers. The wrong manufacturer can result in poor force performance, overheating, quality variations, delay in lead time, and unexpected development costs. Both the technical capabilities and production reliability of a manufacturer need to be evaluated by the buyer before purchasing the product.
1. Do Not Choose Frame Push-Pull Solenoid Manufacturer Based on Unit Price Alone
It is possible to choose the most inexpensive frame push-pull solenoid manufacturer, but the quality of the product might be unacceptable because the manufacturer will use cheaper materials (e.g., worse magnetic materials, wires, springs, or coatings). Compare the technical specification, quality management systems, tooling cost, sample cost, manufacturing cost, and lifetime of the product before ordering.
2. Make Sure the Frame Push-Pull Solenoid Manufacturer Can Provide a Customized Design
In many cases, the dimensions, force, voltage, stroke, mounting holes, terminals, and return spring must be customized. One of the common mistakes when choosing a manufacturer is choosing a company that can only produce standard models without sufficient engineering capabilities. It is necessary to make sure that a qualified frame push-pull solenoid manufacturer can optimize the magnetic circuit, coil, plunger, housing, spring, and mechanical structure for the specific application.
3. Define Push and Pull Forces Precisely
Frame push-pull solenoids are intended to move the plunger linearly in two directions, but it is possible that the forces needed for pushing and pulling are different. The customer should specify the required force at a certain stroke, voltage, temperature, and duty cycle. Never choose a manufacturer based on the maximal or initial value of force. Request the force-stroke curve from the supplier.
4. Take Into Account Operating Duty Cycle and Thermal Performance
Another common mistake is forgetting about the operating duty cycle of a frame push-pull solenoid. An intermittent solenoid might overheat if it is operated continuously. Before ordering the product from any manufacturer, define what kind of duty operation is required (10%, 25%, 50%, or 100%). The supplier should estimate the temperature rise of the coil and advise you on what wire size, resistance, and other parameters you need.
5. Inspect the Quality Control and Testing of the Product
The qualified manufacturer should have specified procedures for material inspection, coil winding, assembling, measuring the electrical characteristics of the product, and evaluating its force, stroke, and other parameters. Ask if it is possible to get the inspection report or custom test procedure for your application. An ISO-certified manufacturing process and internal testing laboratory can give you additional assurance for industrial applications.
6. Inspect Manufacturing and Tooling Capabilities
Frame push-pull solenoids require precision metal components, plastic parts, coils, springs, and assembled magnetic circuits. A manufacturer with in-house or controlled by him tooling, stamping, injection molding, CNC manufacturing, coil winding, and assembling capabilities can provide you with better dimensional control and quality assurance.
7. Check Sample and Mass-Produced Product Consistency
While the prototype might be very good, the mass-produced products can be less consistent. Before accepting the supplier, ask him how he controls the production consistency. The sample approval should include the dimensional measurement, force measurement, voltage measurement, temperature test, noise test, and life-cycle test if it is required.
8. Consider the Lead Time and Stable Supply of the Products
Do not concentrate only on the sample delivery time. Ask the manufacturer about tooling development time, sample delivery time, manufacturing time, minimal order quantity, monthly capacity, and backup manufacturing. A reliable frame push-pull solenoid manufacturer should be able to support your development and stable supply of the product.
